I agree that something is better than nothing.

My grandma had this saying about individual action rippling out like when you throw a stone in the pond. That tends to be my approach to altruism--it's still good if it's small and close to home.

However, at some point, cultural change needs to happen. I believe it is possible, even in this generation, but it needs to be done at a personal level.

And you gave a talk at Solaris? How neat - I was just hearing about that from someone.
